android - 无法在模拟器上运行离子应用程序

问题描述

我正在尝试在 android 模拟器上运行 ionic 应用程序，但我不断收到此错误。

    ANDROID_HOME=C:\Users\Dell\AppData\Local\Android\sdk
    JAVA_HOME=C:\Program Files\Java\jdk1.8.0_171

解决方案

这种不一致场景的可能解决方案如下：

  1. 在 android 平台下的 config.xml 中添加此首选项：

<preference name="loadUrlTimeoutValue" value="700000" />

  1. 每次启动前杀死并重新启动 adb 服务器

adb kill-server adb forward --remove-all adb start-server

  1. 尝试创建一个新的 AVD 并将其作为目标，同时启动 AVD 删除并重新添加 android 平台并重建相同
